GMKtec NucBox G3 Plus Height Extension Stand

Description

Extend the height of the GMKtec G3 Plus by around 14mm to a total ground clearance of 16mm, providing greater airflow for the CPU fan intake underneath.  A quick and crude CPU stress test resulted in a 4°C drop in the 'balanced' mode - your mileage may vary.

No additional hardware required.  The existing feet friction fit into the stand.  The side with the notch goes either front or back since the device isn't perfectly square.

May fit other models with the same footprint: 115mm width, 107mm length, 12mm rubber feet 4mm from the edges.

Cool your G3's RAM and NVME by mounting a fan to the top of the case: https://www.printables.com/model/1339153-gmktec-nucbox-g3-plus-fan-case-80mm-60mm

I also have a stand for the M5 Plus: https://www.printables.com/model/1309654-gmktec-nucbox-m5-plus-height-extension-stand
